“Which are relevant, and which are most important?”
That’s precisely the subjective part.
They could be objective, given a context. Now the choice of context may be a matter of taste or preference. But given a context that we want to ask questions about, we might be able to get objective answers. (E.g. will this hypothetical future person think like me?)
But agree that some subjectivity is involved somewhere in the process.
“What subjective system?”
Some combination of an ethical system and a set of measurable attributes that I care about. I have nothing concrete in mind.
